Atlanta Sun Hours: Understanding Your Solar Investment
Solar Overview
The photovoltaic potential in Atlanta is based on 2,635 annual sun hours, concentrated in May. At 33.75° latitude, Atlanta benefits from relatively consistent solar angles throughout the year, providing stable energy production. Atlanta presents good opportunities for solar energy development, with above-average irradiation supporting viable projects.
Geographic Impact
Positioned at 33.7490° latitude and -84.3880° longitude, Atlanta's geographic coordinates shape its solar resource profile. This latitude offers excellent solar conditions with minimal seasonal variation, typically seeing winter production at 70-80% of summer levels.
Rating Methodology
The "Good" classification reflects Atlanta's solar resource quality, considering its 2,635 annual sun hours and 16.9°C average ambient temperature. The balanced thermal environment supports optimal panel performance and extended system lifespan. The good solar resource enables residential system payback periods of 8-12 years, particularly when combined with available incentives.
